Question

A line with a slope of 3 passes through the point (2, 4). What is the y-intercept of the line?

Answer 1

y-intercept = -2

Explanation:

Use the point-slope form of a line to do this problem.

`y - y_(1) = m(x - x_(1))`

y - 4 = 3(x - 2) Now change the equation to slope-intercept form

y - 4 = 3x -6

y = 3x - 2 So m = 3 b = y-intercept = -2
